How is eaccelerator?

Can anybody provide feedback on eaccelerator? Is it helping, good idea to install? I have installed it on one VPS recently and I'm thinking about installing it on another. Any feedback on it is welcome .

From customer feedback, we have not heard anything negative, only positive results with the performance it offers.

Hopefully some other users will jump in and offer their personal experience.

Currently using MMCache 2.4.6, but I would think the results or issues would be similiar. I'm happy with it from what I can tell.
I had to convert a few of my scripts over to Zend, but so far so good.

I will probably end up using eaccel instead.

Removed mmcache and installed eaccelerator. Everything seems fine and I do notice a performance increase on oscommerce and forum sites for sure.
